IGF-1
Price and cost-per-mg comparison
IGF-1 (insulin-like growth factor 1; somatomedin C) is an endogenous 70-amino-acid polypeptide produced primarily in the liver in response to growth hormone signaling, functioning as the principal mediator of GH anabolic effects through its receptor (IGF-1R) expressed in virtually all tissues, with roles in muscle protein synthesis, bone growth, and cellular proliferation. IGF-1 activates IGF-1R tyrosine kinase to stimulate PI3K/Akt and MAPK/ERK signaling cascades, promoting protein synthesis, cell survival, and glucose uptake in muscle and bone; endogenous IGF-1 levels peak during puberty and decline with age, and GH-stimulating interventions exert many of their effects by elevating circulating IGF-1. The FDA-approved recombinant form, mecasermin (Increlex), is indicated for primary IGF-1 deficiency in children with GH receptor insensitivity syndrome, with multicenter controlled clinical trials demonstrating significant height velocity improvements in this rare pediatric population; this approved indication is specific to a defined hormonal insufficiency condition and is distinct from performance-enhancing or anti-aging uses of exogenous IGF-1. Research-grade IGF-1 is available as a compounded or gray-market compound used outside its approved indication; it is not approved for adult use or performance applications, and risks associated with IGF-1 excess — including effects on glucose homeostasis, potential oncogenic cell signaling, and acromegaly-related comorbidities — are relevant safety considerations for any off-label use.

When IGF-1 prices moved
5 days in the last 120 on which a feed run read comparable IGF-1 prices from 3 or more vendors. Each point is the median $/mg across every comparable listing read that day, sized by how many vendors were read. A log of run days, not a continuous series.

How these prices are computed
The short version. The methodology page has the rest.
Source
Prices are read from each vendor's own store feed or product markup (Vendor feed). Every row says which source it came from and when it was read. Prices parsed from page text are not in this index.
$/mg
Listed price ÷ stated milligrams, converted to USD. Packs are priced on total milligrams. Listings sold per kit, per ml, as capsules or sprays, as blends, or without a stated mass are shown but not ranked.
Population
Active online research vendors only. Clinic, pharmacy and telehealth prices are excluded. Medians and the p25–p75 band are computed over comparable listings, one row per vendor product and size.
Independence. Ranking in this index: 0 paid placements.
PeptideBase accepts no payment for inclusion in this index.
PeptideBase takes no affiliate commission on vendor sales.
Ordering is by price, from scraped data.
